A CurrencyUnit-to-BillingAccountEntry map is persisted in the Registrar entity. It provides flexibility for billing systems that assign different account ids for accounts under different currencies of the same registrar. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=151022753

/**

|
* Combined converter and validator class for key-value map JCommander argument strings.
|
|
*
|
|
* <p>These strings have the form {@code <K-str>=<V-str>,[<K-str>=<V-str>]*} where
|
|
* {@code <K-str>} and {@code <V-str>} are strings that can be parsed into instances of some key
|
|
* type {@code K} and value type {@code V}, respectively. This class converts a string into an
|
|
* ImmutableMap mapping {@code K} to {@code V}. Validation and conversion share the same logic;
|
|
* validation is just done by attempting conversion and throwing exceptions if need be.
|
|
*
|
|
* <p>Subclasses must implement parseKey() and parseValue() to define how to parse {@code <K-str>}
|
|
* and {@code <V-str>} into {@code K} and {@code V}, respectively.
|
|
*
|
|
* @param <K> instance key type
|
|
* @param <V> instance value type
